In the process of teaching medical genetics of undergraduate clinical medicine, the practice and exploration of applying EBM to the bilingual teaching of OSBCM medical genetics are carried out. Using CBL and PBL as the carrier can make up for the shortcomings of a single teaching mode, synthesize the advantages of multiple teaching modes. It starts from integrating the basic theoretical knowledge of medicine and clinical practice knowledge, improving students’ bilingual level of medical genetics, cultivating students’ literature retrieval ability, and promoting early clinical, multi-clinical and repeated clinical consciousness for medical students. Therefore, it is more conducive to cultivate students’ ability to learn independently, accurately analyze and solve problems, improve medical students’ clinical thinking ability and scientific research awareness, improve medical students’ ability of international communication, and lay a solid foundation for improving medical students’ future post competence, innovative spirit and lifelong learning ability.

Spin-orbit,charge-transfer intersystem crossing （SOCT-ISC） can directly overcome the disadvantages of the traditional heavy-atom effect and improve the generation efficiency of reactive oxygen species （ROS）.Since orthogonal molecular orbitals of donor-acceptor （D-A） pairs favor the SOCT-ISC transition,herein aza-borondipyrromethenes （aza-BODIPYs） with 1,7-di-anthracyl groups （An-azaBDP） was successfully prepared,owing to steric hindrance to produce a big dihedral angle between the two molecular orbital （MO）***,according to density functional theory （DFT） and time-dependent density functional theory （TDDFT）,the energy difference between the S1-T1orbitals of An-aza BDP is small and more inclined towards ***-aza BDP can effectively generate singlet oxygen under light ***-aza BDP with light irradiation can induce apoptosis in SW620 cells,and can serve as a potential candidate for the treatment of cancer cells and tumors.
